Renewable Energy Sources Of Energy

Everyone uses a lot of power for lighting, heating, machines, movements, and so much more. All of that energy has to come from an energy supply. Some energy resources are renewable, while others are non-renewable. Energy has various forms and is a very essential part of our everyday lives.

Currently in the U.S. we rely on non-renewable sources to produce our energy such as oil, coal, natural gas and nuclear energy. Although these methods do well producing energy, they also have large down falls environmental, economically, and in other ways that fail to show a promising future. This makes it necessary that we adapt alternative renewable energy methods that do not have these effects, and can insure a promising future.

Society has become more and more reliant of technology as the years have gone past. From the early days, approximated 1.5 million years ago, to today, there has been a significant change on the main sources of domestic energy. One and a half million years ago the main source of energy was sunlight to keep warm and then it progressed to burning wood with friction for fire for cooking. Approximately 6000 BCE, domesticated animals were used to lift heavy items, to transport people, pull ploughs and turn large grindstone to make flour. This also allowed the transport of items to other towns for trade. The industrial revolution came around with the use of burning coal for heat. This allowed ovens to run on coal gas and the coal was used to heat

The State of Michigan in the upper Midwest of the United States currently relies heavily on nonrenewable energy sources including fossil fuels such as coal and natural gas. As we striveto reduce the negative impacts from the use of nonrenewable resources and from our growing population, local and state governments are exploring new, renewable forms of energy, as well ashow to increase demand through conservation. Not all energy alternatives are suited for all locations, so the advantages and disadvantages of current and possible future resources will be examined.

Many centuries ago people did not need much energy. Back then, people used the sun or burned wood and straw for heat. People used the wind force in sails or horses to go anywhere in the world and used animals to do the work humans could not do. Although, humans did use simple machines that could ground grain, pump water, and even utilize steam power. Steam engines transformed over time and by the 18th century the modern steam engine, fueled by coal, could do the job of a team of horses. Since steam engines were much more favorable compared to air and wind power, steam engines were used to power factories and coal was used to heat up buildings.

Renewable energy is currently one of the most preferred energy sources worldwide. Over the past few decades, there has been a raging debate on the capacity of renewable energy to meet the needs of the society. Despite the fact that it has public backing and several benefits over other sources of energy such as fossil fuels, renewable technologies is still doubted by scientists. Being characterised as a type of energy that cannot meet the energy needs of the

Today, most of our energy comes from burning fossil-fuels such as coal and oil. There some inherent problems in basing the entire world 's energy supply upon that kind of fuel, such as the fact that fossil-fuels are nonrenewable and will eventually run out. Burning fossil-fuels also produces copious amounts of pollution that is both harmful to the Earth and to humans. Although alternative forms of producing energy are not as efficient as nonrenewable methods, they are a lot more stable and reliable. The alternative energy market is also continually growing even though it has not reached anywhere near the levels of the traditional coal and oil indexes. Although there certainly are a lot of benefits to using nonrenewable fossil fuels to

Securing a sustainable future for electricity can be ensured by introducing renewable energy sources to develop a sustainable weighting of the three Economic, Environmental and Social pillars of sustainability. It is known today that the world needs sustainable electricity sources to produce energy, as our natural recourses such as coal are running out. The burning of coal for energy produces an output of carbon dioxide, which is the leading cause to global warming the detrimental effects on the future of the environment. The world has access to many sources of renewable energy such as, wind power, solar power, and hydro power. Although, renewable energy does not produce the majority of the worlds electricity as the conversion to renewable energy sources has been difficult due to lack of funding the governments are willing to pay across the world.

Sucient, reliable sources of energy are a necessity for industrialized nations. Energy is used for heating, cooking, transportation and manufacturing. Energy can be generally classied as non-renewable and renewable.....

During the course of history, this country has been seeking new forms of energy that will provide clean energy and also preserve Earth 's lifespan. The use of renewable and non-renewable resources has been a major controversy throughout history; renewable energy such as wind power has been the main focus of this issue. Many would believe wind energy is the best renewable power source because it is the cleanest and most efficient, whereas, others view wind energy as a time bomb that will soon destroy the planet. Alternative energy sources should replace non-renewable energy with wind energy.

The reason behind this topic being chosen is primarily due to the ever-growing energy demands and recent concerns regarding the rate of usage and future availability of fossil fuels and other conventional sources of energy. Also, as per many environmentalists, the excessive usage of such energy sources is affecting the environment which might lead to severe consequences for future generations. To address this issue, many organizations throughout the world have taken various initiatives to find and hence provide the public with alternative sources of energy. They therefore, have been sources of inspiration for many including ourselves to work in this field.

The world currently faces a major problem. This problem is the need for alternative energy sources which can be converted into electricity because the main energy source currently used is coal and the coal deposits will not last forever. The main alternative energy sources that many countries are currently researching are wind, solar, hydro and nuclear. But there is currently another source of energy that is heavily debated to see whether the pros outweigh the cons. This energy source is natural gas. The main reason for the heavy debate of natural gas is not because of the energy source, but rather the mining process of the energy source through the process of hydraulic fracturing. In this report the following topics will be discussed to get a better understanding of natural gas and the hydraulic fracturing process. An overview of natural gas will be discussed. A detail description of the hydraulic fracturing process will be provided. The advantages and disadvantages of hydraulic fracturing will also be compared. Finally the report will look at hydraulic fracturing in a South Africa context and weigh all the information before deciding if the hydraulic fracturing process is advantageous or disadvantageous for the country to use.

British Petroleum and Royal Dutch Shell, two of the world’s largest oil companies, predict that by 2050, one third of the world’s energy will have to come from some type of alternative energy source (Alternative Energy 2015). Constant growth of population, climate changes, and depletion of fossil fuels makes it necessary for renewables to play a bigger role in powering our world. These resources are often thought to be ‘free’ sources of energy because they are naturally occurring events used to form electric power (Alternative Energy 2015). In addition, all of these forms have a large decrease in carbon emissions compared to conventional energy sources

Today 's society uses enormous amounts of energy. *The shadow of our presence on this planet is a result of generations upon generations of production and utilization of energy*. New and alternative sources of energy are being developed to replace the declining accessibility of coal and fossil fuels. Use of renewable energy is a key component in combatting the climate change that has become a major issue in the 21st century. Reducing our impact on the climate as a result of greenhouse gas emissions will not only benefit our generation, but countless generations after us. This technology is not only affordable, but is within reach.

Energy is vital for human survival and development. Most of today’s energy comes fossil fuels and Biomass. However these types of fuels are deplitable and emit green house gases e.g. CO2which leads to global warming. (See Fig 1.1).On the other hand, renewable energy is inexhaustible and does not any produce green house gases that can pollute the environment. Therefore there is need to shift to renewable sources of energy.
